Specification of Letters Patent.

latented Nov. 13, 1906.

Application filed April 25, 1904. Serial No. 204.812.

To all whom it T11/wy concern: v

Be it known that I, HANS JACOB MOETEN- sEN, a citizen of the United States, residing at the city of Baltimore, State of Maryland, have invented certain new and useful Improvements in Non-Reiillable Bottles, of which the following is a specification.

The present invention relates to improvements in non-reiillable bottles and will be described in connection with the accompanying drawings, in which- Figure l is a longitudinal sectional view through a portion of a bottle constructed in accordance with the present invention, showing the position of the parts when the bottle is standing upright. Fig. 2 is a similar view showing the position of the parts when the bottle is inverted. Fig. 3 illustrates the operation of the parts by which refilling of the bottle is prevented. Figs. 4 and 5 are detail views of the guard for preventing access to the valve at the inner end of the bottle-neck. Fig. 6 is a detail view of the valve.

Referring to the drawings, in which like reference characters designate corresponding parts in the several figures, 1 designates the body and 2 the neck of a bottle, which may be of any suitable size and form. A valve 3 is arranged Within the bottle-neck, being preferably located at the inner end of the neck, as shown. This valve, which is made in the form hereinafter described, maybe of any suitable material, although preferably it is made relatively light, so that it will float and be forced toits seat by any liquid that might enter the neck of the bottle from the outer end under pressure. As shown, it consists of a body of cork or other material of low specific gravity, which is attached to and directed in its movements by a suitable guide 4, having guiding iianges or pins that extend into the body of the bottle. The body of the valve is provided with a peripheral flange 4a, which bears closely against the valve-seat when the valve is closed, and an annular groove 4b is formed about a reduced portion of said body, as shown most clearly in Fig. 6. The other portions of the valve-frame may be either formed of wire, as shown in Figs. l to 3, or be made integral with said body, as shown in Fig. 6.

A valve constructed in the manner above `described has been found by practical use to from or to the bottle when it is closed. The special form of the head prevents ine particles of solid matter from holding the valve away from its seat, which is one of the objections to the forms of valves heretofore proposed for similar uses.

Within the bottle-neck, between the outer end thereof and the said valve, is arranged a lock or guard constructed to provide a tortuous passage or passages through which liquid can freely pass, but which will e'ectually prevent the insertion of anything designed to actuate or interfere with the action of the valve and will act to keep in place the balls hereinafter described. As shown, this lock or guard-is made in the form of a plug consisting of a central core or stem 5, provided with a plurality of longitudinally-extending radially-projecting webs 6. From both sides of each of said webs 6 there project a series of baffle-plates 7 of the form shown. suitable number of such baffle-plates may be provided and they are so positioned and arranged that those on one of said webs overlap or project partially over the corresponding plates on the other webs. In the embodiment of the invention illustrated rthere are iive of such plates on each web, two proj ecting from one face and three from the opposite face thereof. The number may, however, be varied as desired, according to the length, &c., of the guard-plug. The stem or core 5, webs 6, and baie-plates may be all formed integral-for instance, of glass molded to the desired form. Any suitable material may, however, be employed. Said lock or guard is held firmly in place in the bottleneck by means of a resilient fastener. As shown in the drawings, an annular groove 8 is formed in the inner surface of the neck 2, and in the outer longitudinal edges of the webs 6 are formed notches or grooves which aline with said groove 8 when the guard is in place. A split metal ring 9 is fitted about the guard and lies in the groove, which, as above described, is formed partly in the bottle-neck and partly in the guard. This part of the invention (illustrated particularly in Fig. 4 of the drawings) affords a very secure fastening for the guard, but also practically prevents removal thereof without destroying the bottle. Within the space between the valve and said lock or guard are arranged three relatively heavy balls 1l, which in con- IOO y nection with said lock or guard constitute a lock to forcibly close the valve whenever the bottle is in any other than a vertical position. Such. balls or spherical weights 1 l are of such diameter, construction, and weight that they will provide a continuous abutment or pressure device between the lock or guard and the valve when the bottle is inclined or tipped from the vert-ical and will operate, therefore, to hold said valve to its seat until and after the bottle has been inverted, as shown in Fig. 2.`

A cork or other stopper 12 may be employed to close the outer end of the bottleneck or mouth of the bottle.

rIhe operation of the valve mechanism above described will be clearly understood from the drawings. It will be seen that in every position of the bottle, except when the neck thereof is vertical, the spherical weights will form a continuous pressure device from the lock or guard to the valve and hold the latter closed. Therefore it will be impossible to introduce liquid into the bottle. The valve being very light and floatable will be moved into closed osition should an attempt be made to force liquid into the bottle under pressure while holding it in the position indicated in Fig. 2.

By this invention the inner surface of the bottle-neck may be made perfectly smooth and so as not to present any projecting parts which might obstruct the flow of liquid or catch and hold dust, &c.

The balls 11 and bottle-neck are of course so proportioned that the valve hereinbefore described will Abe properly effective; but it is not necessary to provide special seats or abutments in the sides of theV bottle-neck to coact with said balls. Without limiting myself to the precise construction and arrangement of parts shown, I claim as my inventionl. rIhe combination with a bottle having a neck which is of greater diameter adjacentl its inner end than at its outer end, of a valve arranged at the inner end of the bottleneck,

a lock or guard secured within the neck of the bottle, and three spherical bodies arranged within the space between said lock or guard and the valve, the size of said bodies and the form of the bottle-neck causing all of the bodies to contact with the valve when the bottle is in upright position, and two of said bodies contacting, respectively, withl the lock or guard and the valve whenever the bottle is positioned to allow the valve to open, and the other body being adapted to automatically pass between the two aforesaid and maintain a continuous pressure device between the guard and valve when the bottle is inverted and while it is being turned into upright position.

2. The combination with a bottle having a valve-seat formed at the inner end of its neck, of a valve consisting of a frame extending into the body of the bottle and a body having an annular groove formed therein and also provided with a peripheral flange adapted to enga e the valve-seat, a lock or uard secure within the neck of the bott e, and a plurality of balls or sphericaly weights ar-.

ranged within the neck between the valve and said lock or guard, substantially as described.

8. The combination with a bottle having a suitable valve-seat in its neck, of a valve hav ing a downwardly-projecting annular flange to cooperate with the valve-seat, and an an nular groove adjacent to said flange.

4. The combination with a bottle having a valve-seat in its neck, of a valve cooperating with said seat and provided with an annular flange la and an annular groove 4b adjacent thereto, and automatic means for closing the valve, for the purpose described.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

HANS JACOB MORTENSEN.
